The Liverpool Jewish Record Office has a record of my grandmother's marriage, presumably copied from her ketubah. Where her surname should be is the word "Kantoor" which I assumed was the equivalent of "Cantor", so I recorded it as her maiden name. It turns out that it is german for "office" and meanwhile about a thousand members of the Kantoor list (none of them named "Kantoor") have been appended to my tree. In consequence, I keep getting "smart (sic) matches" none of which I recognise as relatives. I think the solution to this problem would lie in deletion of this unrecognised branch - until I do, a lot of people will be getting "Office copies" about relatives they do not have!
